This adaptability is useful for those who may be working with different wall types in construction or home improvement tasks. On the downside, some users might find that the device requires two AAA batteries, meaning you’ll need to keep replacements on hand. While the battery life is generally good, it’s essential to consider this aspect if you're planning on using the device frequently. The device’s weight (11.4 ounces) and plastic construction might not feel as robust as other stud finders made with heavier materials, but this also makes it more portable.
